heyprof – An AI-Powered Platform for Teaching and Learning

Architecture, Capabilities, and Pedagogical Design

Volker Reichenberger · Dirk Schieborn · Version 2.0 · 23 September 2026

At its centre is an AI tutor that does not answer from a language model’s world knowledge but from the course: the lecturer’s slides, script and recorded lecture, the current exercise with its model solution, and the student’s own work so far. It guides Socratically instead of handing out solutions.

The white paper covers the architecture, the features for lecturers and students, the more than 590 interactive VisuApps, the AI integration, the pedagogical principles and data protection.
